Description

Technical Field

[0001] The utility model relates to heat transfer paper, in particular to heat-resistant heat transfer printing base paper. Background Art

[0002] Transfer printing involves transferring various patterns onto an intermediate carrier through a printing or printing process, and then transferring the pattern from the intermediate carrier to the substrate using appropriate pressure and temperature. Thermal transfer is a major transfer method. Thermal transfer involves printing a pattern onto heat-resistant thermal transfer paper. Heat and pressure are applied to transfer the ink pattern to the finished material. Thermal transfer paper, the carrier of the thermal transfer image, is crucial to the color vividness and realism of the transferred image.

[0003] However, the quality of traditional heat-resistant thermal transfer paper is poor. It is just a thin piece of paper with poor pressure resistance. During the transfer process, the transfer equipment directly pressurizes and heats the thermal transfer paper, which can easily cause damage to the thermal transfer paper and affect the transfer effect. Utility Model Content

[0004] The purpose of the utility model is to provide a heat-resistant heat transfer printing base paper, which has the characteristic of effectively improving the pressure resistance effect.

[0005] The technical solution of the utility model is as follows: the heat-resistant thermal transfer printing base paper includes a paper base layer and a high-temperature resistant flexible and pressure-resistant bottom layer distributed up and down, a grid-shaped heat-conductive carbon fiber layer is provided between the paper base layer and the high-temperature resistant flexible and pressure-resistant bottom layer, and a group of air holes are provided on the bottom surface of the high-temperature resistant flexible and pressure-resistant bottom layer; the paper base layer includes two layers of thermal transfer base paper layers distributed up and down, and a glass fiber layer is provided between the two layers of thermal transfer base paper layers.

[0006] In the aforementioned heat-resistant heat transfer printing base paper, the bottom surface of the paper base layer is further provided with a polytetrafluoroethylene microporous membrane layer.

[0007] In the aforementioned heat-resistant heat transfer printing base paper, the high-temperature resistant flexible pressure-resistant bottom layer is a high-temperature resistant organic silicone layer.

[0008] Compared with the prior art, the present invention is composed of a thermal transfer base paper layer and a high-temperature resistant flexible pressure-resistant bottom layer, which can effectively improve the pressure resistance of the thermal transfer base paper layer; and a heat-conducting carbon fiber layer is provided between the two layers, and air holes are provided on the surface of the high-temperature resistant flexible pressure-resistant bottom layer, so as to ensure good thermal conductivity and uniformity of thermal conductivity, and ensure the smooth progress of thermal transfer. At the same time, the paper base layer of the present application is composed of two layers of thermal transfer base paper layers and a glass fiber layer, so that the paper base layer has good flexibility and tear resistance, and can also improve a certain degree of pressure resistance. In summary, the present invention has the characteristics of being able to effectively improve the pressure resistance effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] By pasting a polytetrafluoroethylene microporous membrane layer on the back of the paper base, it has good waterproof and breathable effects.
